Measurement and Analysis of the Relationship Between Economic Development and Environmental Protection of Shandong Province

The EKC curve is often used to describe the relation between economic growth and environmental degradation,and typically in the inverted U shape With the 1988-2002 economic and environmental data in Shandong Province,models of industrial waste discharge per unit GDP and industrial waste discharge per capita GDP have been established,and the relationship between environment protection and economic development has been analyzed.By industrial waste discharge per unit GDP model,we find that the pollution load per unit GDP displays a downward trend, which indicates the adjustment of industrial structure has yielded significant results.By the model of industrial waste discharge in relation to GDP per capita,the paper finds that the relation of economic development and environmental pollution in Shandong province does not conform to the typical shape of EKC,but conforms to the three-time function,in which,the waste water EKC takes the shape of U plus inverted U,and the simulated calculation values of its two turning points are 3416 yuan and 9975 yuan respectively.The curves of waste gas and solid waste are both taking the shape of the left half part of inverted U,and have not reached their turning points yet.In conclusion,the improvement of environmental quality can't occur automatically,economic income,national or regional environmental policy and industrial process are all the factors that lead to EKC in Shandong Province.
